Description
巻き取られた紙ロールの巻き取り硬度の測定器に関する。The present invention relates to a measuring instrument for the winding hardness of a wound paper roll.
従来、製紙産業で製品として出来上った紙を巻き取り、紙ロールとして出荷するが、巻き取りが均一にならないと、巻き戻し中に紙切れ事故を起こしたり、印刷工程で印刷不具合が発生したりする。このような事故、不具合を予防するために紙ロールの巻き方の均一性をチェックするために出荷前に紙ロールの巻き取り硬度を測定して巻き取りの均一性を検査する必要がある。硬度測定方法としては木棒により叩いて音を耳で聞く打音法、あるいはシュミットハンマーを用いた硬度測定法が一般的であるが、打音法は検査員の感に頼るものであり、検査データも曖昧なものとなってしまう。一方、シュミットハンマー法は検査員が測定位置にハンマーの先端を押し付けてばねを圧縮してそのばねの力を利用してハンマーが測定対象に当ったときの反発力を測定するので、測定点が非連続であり測定にも時間を要する。Conventionally, paper produced as a product in the paper industry is wound up and shipped as a paper roll. However, if the winding is not uniform, a paper breakage accident may occur during rewinding, or a printing failure may occur during the printing process. To do. In order to prevent such accidents and malfunctions, it is necessary to inspect the winding uniformity by measuring the winding hardness of the paper roll before shipment in order to check the uniformity of the winding method of the paper roll. As a hardness measurement method, a hitting method in which a sound is heard by hitting with a wooden stick or a hardness measurement method using a Schmitt hammer is generally used, but the hitting method depends on the feeling of the inspector. The data will also be ambiguous. On the other hand, in the Schmitt hammer method, the inspector presses the tip of the hammer to the measurement position and compresses the spring and uses the force of the spring to measure the repulsive force when the hammer hits the object to be measured. It is discontinuous and takes time to measure.
さらに、シュミットハンマー方式では各測定点のデータは数値として捉えられるが、その測定位置は検査員が見当をつけて決めるものであり、正確性を欠くきらいがある。Furthermore, in the Schmitt hammer method, the data at each measurement point is captured as a numerical value, but the measurement position is determined by the inspector with a sense, and there is a tendency to lack accuracy.
本考案では、紙ロールの巻き取り硬度の測定を紙ロールの幅方向に検出部を移動させることにより連続測定することを可能にし、あわせて測定結果のデータを幅方向に対応したグラフ表示できるようにすることを目的とする。In the present invention, it is possible to continuously measure the winding hardness of the paper roll by moving the detection unit in the width direction of the paper roll, and to display the measurement result data in a graph corresponding to the width direction. The purpose is to.
上記問題を解決するための本考案について記述する。
紙ロール面を連打するハンマーと、そのハンマーが紙ロール面に当って停止するまでの減速度を測定し、そのハンマーの移動距離を測定する機能により、紙ロールの幅方向にハンマーを連打ささせつつ移動させて、紙ロールの幅方向の巻き取り硬度の変化を測定させ、あわせて紙ロール幅方向の変化グラフを描かせる。The present invention for solving the above problems will be described.
A hammer that repeatedly strikes the paper roll surface, and the deceleration until the hammer stops when it hits the paper roll surface, and measures the distance traveled by the hammer, allows the hammer to be repeatedly hit in the width direction of the paper roll. Then, the change in the winding hardness in the width direction of the paper roll is measured, and a change graph in the width direction of the paper roll is drawn together.
本考案の実施例を図1に従って説明する。An embodiment of the present invention will be described with reference to FIG.
電磁コイル1とばね2を利用して連続して往復運動する小型ハンマー3により、測定対象の紙ロール9を連打するようにする。The paper roll 9 to be measured is continuously hit by a
この小型ハンマー3の往復運動している位置を測定するハンマー位置検出部4を小型ハンマー3に近接して設置する。A
ハンマー位置検出部4が検出した小型ハンマー3の位置情報を取り込んで小型ハンマー3が紙ロール9に当って停止するまでの減速度(マイナス加速度)を計算する減速度計算部5により、減速度をデータ処理部に送出する。The
紙ロール9の表面を小型ハンマー3が移動する移動量を計数する移動距離測定部6により小型ハンマー3が移動した距離を測定してその移動距離データをデータ処理部7に送出する。The distance traveled by the
データ処理部7は、ハンマー位置検出部4からの減速度データと移動距離測定部6からの移動距離データを用いて移動距離に対応した減速度を記憶する。The data processing unit 7 stores the deceleration corresponding to the moving distance using the deceleration data from the hammer
これらの小型ハンマー3、ハンマー位置検出部4、減速度計算部5、移動距離測定部6、さらに紙ロール9の表面上を容易に移動させられるように複数のローラー10及びケースを測定ヘッド8として一体化させる。These
この測定ヘッドを紙ロールの幅方向に端から他方の端までを移動させて連続測定を行うことにより紙ロールの幅方向の減速度が連続的に測定されて、同時に得られた移動距離データを用いて幅方向の減速度変化のグラフをデータ処理部7で描画できる。By moving this measuring head from one end to the other in the width direction of the paper roll and continuously measuring the deceleration in the width direction of the paper roll, the moving distance data obtained at the same time is measured. By using this, the data processor 7 can draw a graph of the deceleration change in the width direction.
減速度は硬度と直接の相関があるので表示されたグラフは紙ロールの巻き取り硬度の変化を表し、巻き取り硬度が均一か否かを短時間に容易に判断でき、かつ測定結果はデータ処理部に記憶されるので検査成績書等への再利用が可能となる。Since the deceleration has a direct correlation with the hardness, the displayed graph shows the change in the winding hardness of the paper roll, it can be easily determined in a short time whether the winding hardness is uniform, and the measurement results are data processed Since it is stored in the department, it can be reused for inspection reports.
